Figure 2 is a transverse sectional view which in turn will imparta rearward pull taken on line 2 2 of Figure l. on the end of the bar 6 to which the chain is 50 Figure 3 is a rear view of the outer end of connected, 3

Connected by means of links to the ends of the large bar 24 are doubletrees 26, to the ends of which are connected by means of links 27, singletrees 28, and to which -singletrees draft animals are attached. As the four draft animals impart a rearward pull on the end a of the forward transverse bar 6, a forward pull is imparted on the end b of the intermediate bar 7 which will force the anti frictional roller 29 of the intermediate `bar into engagement with the rear side of the bar 6, and any movement transversely of bars 6 and 7 in relation to each other, will not cause binding or damage, as the anti frictional roller will freely rotate. At the same time forward pull is imparted on the end c of the intermediate bar 7 by a single draft animal, and as the leverage is relatively short7 the draft between the single and the four animals will be equalized.

From the above it will be seen that a draft equalizer is provided, which is simple in construction, parts reduced to a minimum.

The invention having been set forth what is claimed as new and useful is:

The combination-with a live horse evener,

. means to which four horses may be attached,

a draft bar, a transverse bar pivoted to said draftbar, a sheave carried by one end of the transverse bar, to one side of the draftbar, a flexible member attached to the four horse draft means and extending rearwardly over the sheave and forwardly, a forward transverse bar carried by the draft bar, and to one end of which the flexible member is attached,

an intermediate bar, a link connection between the intermediate bar and the forward transverse bar adjacent the draft bar, a link connection between the rear transverse bar and the intermediate bar to the outside of the' lirst mentioned link connection, means for Aattaching a single draft animal to the outer ends of the intermediate bar and an Y Vanti'frictional roller engagement between one endof the intermediate bar and the forward transverse bar.

In testimony whereof I hereunto affix my signature.
